Organizing method for products being searchable based on gallon, quart, dimensions, etc.

[Penrose]

Question: What is the best setup so when a shopper searches or products based on sizes (gallons, quarts) and dimensions (inches and feet) they can easily find them? Our site sells various products that have several different sizes - Quart, 1 Gallon, 5 Gallon, etc. Also we sell various products that have various sizes and dimensions - 1 Inch, 11"x17", 12ft, etc.

We do not link products by sizes and dimensions in our menu structure and we use "Smart Search & Filter" for  search. And if you you run a search and scroll down on the left under "Collections" it lists 1 Gallon, 1 Inch etc.. because (before I took over) the products sizes/dimensions were setup in individual Collections. So, there will be a collection titled "1 Gallon" with just one product in it - a product that comes in 1 Gallon size. And so on and so on.

Having all these collections with 1 or 2 products in them based on sizes and dimensions seems like a waste. Could anyone share best practices for this type of search by size/dimension? 

thank you

This search and filter app https://apps.shopify.com/ultimate-search-and-filter-1 let your users search by a combination of Gallon, Quart, Dimensions, Etc. Suppose those fields are stored in product option or variant metafield, the Ultimate Search engine easily identifies the correct product variants and present them to your end-user. Since you have some special characters in your text, i would recommend contacting the team to have them set it up for you.
